  2. Outline • Project overview • Block diagram • Design challenges • Individual contributions • Project demonstration • Questions / discussion

  3. Project Overview • Instrumentation and analysis system for a aluminum-fuelled hydrogen-powered golf cart. • Primary goal: aid in very promising hydrogen-fuel technology codenamed “Alumoline”. • Sensors to monitor important hydrogen system readings. • Dashboard display similar to Toyota Prius and Nissan GT-R.

  4. Block Diagram 36 V Battery Pack 5V-3.3V Regulator 12V-5V Regulator 36V-12V Regulator VCC VCC (5V) SPI 4 wire Freescale 9S12C32 ATD0 SD Card Thermocouple Amplifier (A) Thermocouple (A) ATD1 Thermocouple Amplifier (B) Thermocouple (B) ATD2 Pressure Sensor (A) ATD3 ATD4 Pressure Sensor (B) SCI Hydrogen Leak Detector ATOM Board VCC (12V) VGA USB 7 Inch Touch Screen(USB) LCD VCC (12V)

  5. Design Challenges • Power Supply Design • Insufficient on-board power to power LCD • Unable to utilize open source SD FAT16 Library

  6. Design Challenges (cont’d) • Unable to safely monitor water levels • Polling vs Interrupt Driven SCI (for micro)

  7. Individual Contributions • Naman Chopra • Suan-Aik Yeo • Darin Tanaka • Ronny Wijaya

  8. Naman Chopra • Provide team with a vision of project objectives • PCB Soldering/Packaging/Integrating into vehicle • Sensor and parts selection • Intervene when necessary to aid the group in resolving issues • Encourage creativity, risk-taking and constant improvement • Coordinate team logistics

  9. Suan-Aik Yeo • Team and project organization • Power supply design • Microcontroller programming • Interface microcontroller with SD card • Intel Atom motherboard setup and configuration

  10. Darin Tanaka • Intel Atom board configuration to use javax.comm API • Design of high level RS-232 protocol • Java GUI • Microcontroller Communication code • Miscellaneous (PCB reviewing, Parts Ordering, overall system design)

  11. Ronny Wijaya • Develop the PCB through the PADS software • Helped Naman in soldering and packaging • Tested the PCB during the building process • Miscellaneous (parts ordering, overall system design)

  12. Project Demonstration • An ability to receive and correctly record values from various sensors. • An ability to give appropriate warnings and troubleshooting instructions if a sensor detects something wrong. • An ability to store data on external memory. • An ability to use a touch screen to send commands to the microcontroller to control the logging of data and to provide a user configurable display for the logging of data from multiple sensors. • An ability for the microcontroller to receive and execute commands to remotely enable, disable and control the sampling rate of multiple sensors. Demo PSSCs 1-5

  13. Questions / Discussion
